SmallRig Filter Frame (4 x 4") 3648

The SmallRig 3648 filter frame holds a 4 × 4" filter in Star-Trail and Revo-Arcane matte boxes. It slides into the stage in one move, a safety lock keeps it from dropping out, and the aluminium frame resists fingerprints.

The SmallRig 4 × 4" filter frame 3648 belongs to the Star-Trail and Revo-Arcane matte boxes and helps balance exposure in difficult light — you can slide several filters into the matte box one behind the other. The quick-release frame is made of aluminium alloy with an anti-fingerprint finish and has a safety lock that keeps the filter from sliding out.
